SPECIFICATION forming part of Letters Patent No. 447,599, dated March 3, 1891.

Application filed November 17,1890. Serial No. 371,696. No model.)

To @ZZ whom, t may concern:

Be it known that I, CHRISTIAN F. BACHLER, ot' Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Atomizers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which Vit appertainsto make and use the same, reference being had to the ac` companying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to certain improvements in atomizers. The devices of this class ordinarily employed become loose and allow vent at the cork or stopper, hence allowing the pressure in the bottle to reduce, and,fur ther, they become clogged and can only be used in certain bottles.

The object of this invention is to provide an improved atomizer exceedingly simple,`

cheap, and durable in construction, and extremely effective and sure in operation, and which will overcome all disadvantages of the present devices of this character, will prevent all leakage at the stopper, can fit almost anysized bottle, and can be taken apart for cleansing or repairing. These objects are accomplished by, and this invention consists in, certain novel features of construction and in combinations of parts more fully described hereinafter, and particularly pointed out in the claims.

Referring t0 the accompanying drawings, Figure l is a sectional elevation of a bottle, showing the atomizer therein in elevation. Fig. 2 is a longitudinal section of the atomizer, the liquid-discharge tube being shown in elevation. Fig. 3 shows the various parts of the atomizer separated and in elevation. Fig. 4 is an elevation of the discharge end of the preferred form of liquid-tube, and Fig. 5 is a section showing the preferred form of liquid-tube in the discharge end of the airchamber.

In the drawings, the reference-letter a indicates any suitable bottle. b is the liquiddischarge tube of the atomizer of a length to extend down into and almost to the bottom of the bottle and project above thesame,

with the upper end bent at or substantially at right angles and having its discharge end slitted back, substantially as shown at c. An air-inlet tube d surrounds the upper portion of the liquid-discharge tube and extends into the bottle. This air-tube is larger in diameter than the liquid-tube, forming an annular air-passage around the same, open at the top to the outer atmosphere and at its inner end into the interior of the bottle. Theinner end of the large air-tube is slittted or slotted longitudinally, forming spring-iingcrs c, which bear against the discharge-tube, while the slits form openings from said annular air-passage into the bottle. This air-tube also forms the stem or spindle of an expansible bottle-stopper, and is exteriorly screw-threaded the upper portion of its length. Near its lower end this tube has an exterior annular collar f rigid thereon, (preferably integral therewith) against which the lower end of the expansible rubber tube g, slipped onto the tube, ts. h is the upper movable member of the stopper slipped onto said tube and bearing down on said elastic ring, tube, or member and having the upper exterior annular ilangez' to rest on the upper edge of the bottle-neck. j is a washer, and 7e' is the winged nut adjustable on the threaded portion of said air-tube to operate the stopper. An air bulb or chamber Z is located on the upper end of said air-tube surrounding said bent end of the dischargetube. Said chamber is preferably formed integral of metal with a screw-threaded opening m in its bottom opening into the large portion of the chamber and screwed onto the upper end of the air-tube, so that the air can pass from said chamberinto the air-tube. At one end said chamber has the elongated discharge-mouth n, beveled outwardly at its outer end, and at its opposite end a screwthreaded opening o, into which the perforated piece p screws. The discharge-tube extends up through the air-pipe into said chamber with its bent end extending into said contracted discharge, but not completely through the same, and so as to leave a narrow air-passage around said slitted end of the dischargetube. The central portion of said bulb preferably bulges out to form an enlarged airchamber which serves as a reservoir, causing IOC some of the air to How into the air-tube and the remainder to pass through the contracted discharge-opening, thereby creating sullicient pressure to force the liquid in the bottle out through the disch arge-tube, while the air pass ing out around the slitted discharg'e end of said tube atomizes the liquid and carries it out with great force in line spray, the spray being ejected in a large volume and to a con siderable distance.

In order to render the device capable of use in bottles ot' various depths, the liquiddischarge tube below the air-inlet tube may be made telescopic, as shown. The lower sliding section 1 may be closed at the lower end and provided with side apertures 7', so that it can rest on the bottom of the bottle, and hence take up all of the liquid in the bottle.

The prongs or fingers s,t`ormed by the slits at the end of the liquid-diseharge pipe. are preferably flared ou t, (see Figs. a and 5,) hence holding the tube in the center of discharge n and against movement in the bulb; also causing the liquid to be thoroughly atomized.

The atomizer can be applied to almost any bottle. The stopper lforms an air-tight joint within the neck of the bottle, which cannot wear loose and allow vent of air, and holds the parts rigid and the liquid-tube against swinging in the bottle.

All parts oi' the article are made separate and are removable and interchangeable, and the article can be taken completely apart to clean, replace, or repair the various parts, and all interior portions are accessible, so that theycan be cleaned and prevented from clogging.

The many advantages and great utility of the article are obvious.

This article is adapted for various uses, such as spraying tobacco, clothes, extracts, or any liquid.

l. In combination,the liquid-discharge tube having the upper discharge end, the air-inlet tube surrounding said discharge-tu be, the airchamber carried b y the air-tube and surroun ding the discharge end of said liquid-tube, and an expansible bottle-stopper to support said atomizer, consisting of an expansible section and rigid sections on and surrounding said air-tube.

2. In an atomizer, the combination of the liquid-tube, the air-inlet tube exteriorly threaded having the rigid exterior collar, the elastic and sliding members of an expansiblc stopper on said air-tube, and the expanding nut of the stopper on said tube.

3. The atomizer having the lower portion of its liquid-discharge tube telescopic, substantially as described.

l. In an atomizer, the combination of the inner liquid-tube, the air-tube removably on the same and having the threaded upper end and a stopper, the air-chamber having the elongated contracted discharge and the small threaded opening opposite said discharge, and the threaded bottom opening screwed onto the upper end of said air-tube, and the contracted mouth -piece having the small threaded end screwed into said opening opposite the discharge, as set forth.

In testimony that I claim the foregoing as my own I afiix my signature in presence of two witnesses.

CHRISTIAN F. BACHLER.
